3. PROJECTILE MOTION is any motion that
is solely affected by the pull of
gravity
Free-fall
Horizontal
Projectile
Projectile at an
angle
• The object is moving
in one dimension only
(vertical)
• The angle of release is
90° from the
horizontal.
• The object is
moving in two
dimensions.
• The angle of
release is 0° from
the horizontal.
• The object is moving
in two dimensions.
• The angle of release
is above 0° but
below 90° from the
horizontal.

6. CHARACTERISTICS OF A HORIZONTAL PROJECTILE
What is its initial horizontal velocity
(Vix)?
What is its initial vertical velocity
(Viy)?
What have you noticed about the
velocities in the x axis?

Is there a value for initial horizontal velocity?
What have you noticed on the magnitude of horizontal velocity in each
point?
Is there a value for initial vertical velocity?
What happens to the vertical velocity of the projectile as it moves
upward?
What happens to the vertical velocity of the projectile as it reaches its
highest point?
What happens to the vertical velocity of the projectile as it moves
downward?
